I had a rough one last time I brewed.
First AG weighing my own grain, I assumed I could use a bathroom scale and just subtract the weight of the bucket. The theory makes sense, but it didn't work out in reality. Then while milling, I got a chunk of plastic or something in my mill, so it wasn't working like it should. After troubleshooting that, and getting ground up all of my grain, I filled my MLT and added my water, Boy this is doughy! I ended up with 25lb of grain (twice my recipe) in my MLT, so I add more water... Then after I finished mashing, the sparge went well, aside from burning my hand lifting hot vessels, etc, but I need a pump. After burn-care, I got quite a few boil-overs. Then I ended up only getting half of my wort out of my kettle because my hoses got clogged with hop leaves (I should have been using pellet, decided to try whole-leaf). I tried to use my pickup tube to drain the kettle - no dice, and that's now melted.
I ended up using 25lb of grain, burning my hand, breaking a drill (that I didn't really want, but meh), and only getting half of the wort out. It was a rough day. I learned a lot, but boy...
Now my wish list includes a pump, a pickup tube, and a scale, in addition to the previous entries!
